Reap pattern

Description Usage Arguments Details Author(s) See Also Examples

Asynchroneously return a value

1	Sow(..., sow_field = "default")

`...`	value(s) to be returned
`sow_field`	tag to indicate a pool of values into which the value(s) are to be stored, defaults to 'default'

This function stores values into the package environment, so that they can later be retrieved by the Reap function. A ReferenceClass is used to implement the storage logic. Nested calls of Reap/Sow are possible as a stack is internally maintained.
